Exploring the recycling model of Phobos formation: rubble-pile satellites

Gustavo Madeira, Sebastien Charnoz, Yun Zhang +4

Phobos is the target of the return sample mission Martian Moons eXploration by JAXA that will analyze in great details the physical and compositional properties of the satellite fr…

Observable tests for the light-sail scenario of interstellar objects

Wen-Han Zhou, Shang-Fei Liu, Yun Zhang +1

We scrutinize the light sail scenario of the first interstellar object (ISO) 1I/2017 U1 (`Oumuamua) by making comparisons between physical models and observational constraints. The…

Orbital migration and circularization of tidal debris by Alfvén-wave drag: circumstellar debris and pollution around white dwarfs

Yun Zhang, Shang-Fei Liu, Douglas N. C. Lin

A significant fraction of white dwarfs (WDs) exhibit signs of ongoing accretion of refractory elements at rates -- kg s, among which, 37 WDs were detected to…

Tidal distortion and disruption of rubble-pile bodies revisited -- Soft-sphere discrete element analyses

Yun Zhang, Patrick Michel

During close approaches to planets or stars, the morphological and dynamical properties of rubble-pile small bodies can be modified, and some may catastrophically break up. This ph…

Tidal fragmentation as the origin of 1I/2017 U1 ('Oumuamua)

Yun Zhang, Douglas N. C. Lin

The first discovered interstellar object (ISO), `Oumuamua (1I/2017 U1) shows a dry and rocky surface, an unusually elongated short-to-long axis ratio , a low velo…
